Can someone please help me?

An individual's phone number contains seven digits, not including the area code, from the set A shown below.
A = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

Set B represents the digits in Brent's phone number.
B = {5, 5, 5, 3, 0, 9, 9}

Set C represents the digits in Charlie's phone number.
C = {8, 6, 7, 5, 3, 0, 9}

How many even numbers are in the set ∼(B ∩ C)?

Whats the ~ mean?

I don't know.
All it is asking is how many even numbers in sets B and C.

anonymous · Answer

That doesn't really help... ):

B = {5, 5, 5, 3, 0, 9, 9} 
1 even number, 0.
C = {8, 6, 7, 5, 3, 0, 9}
3 even numbers, 0 6 and 8.

I think ~ means opposite, so

Ah, the symbol ∼(B ∩ C) means
which even numbers match in both sets?

shamil98 · Answer

B = {5, 5, 5, 3, 0, 9, 9} 
C = {8, 6, 7, 5, 3, 0, 9}
Only even number that matches from both of these sets is zero.
